encoding/gocode: add Go code generator
Also:
- add gocodec used by generator
- added ability to create temporary Runtime (for concurrency)
- removed index freezing
The latter was only for precondition checking of
internal code. At the same time, freezing could
lead to spurious races if Runtime is used
concurrently.
Note:
- gocodec is a separate package as it is useful
on its own and that way it can be used without
pulling all the dependencies of gocode.
